This new comedy from Academy Award-nominated director Jason Reitman (UP IN THE AIR) and Academy Award-winning screenwriter Diablo Cody (JUNO) centers on Marlo (Academy Award winner Charlize Theron), a mother of three including a newborn. When Marlo is given a night nanny by her brother (Mark Duplass), she is initially hesitant to accept the extravagance but comes to form a unique bond with the thoughtful, surprising and sometimes challenging young nanny named Tully (Mackenzie Davis).

Charlize Theron is riveting in her Oscar-winning performance as one of America's first female serial killers, Aileen Wuornos. A highway prostitute in Florida, Wuornos suffers one too many degradations and ultimately snaps, killing her clients so that she can steal their money without offering up her own body. Christina Ricci co-stars as Selby, Wuornos' lover, who dissolves into a jittery, frightened mess during the course of the nine-month killing spree.
